The reason for your problem is this: MetaPost, when called normally, 
processes the TeX input as plain TeX, not as LaTeX.  Thus, it's not 
surprising that your code worked fine until you included LaTeX-specific macros.

There are two methods that one can use to instruct MetaPost to process the 
TeX parts of the input file with LaTeX instead of plain TeX.  The first is 
to put a line containing just


as the first line of the file.  This is the simplest method, but it doesn't 
work on all systems.  Alternately, you can set an environment variable TEX 
to "latex", or run mpost with a command-line option, like so:

   mpost --tex=latex <myfile.mp>

where <myfile.mp> is the name of your MetaPost file.

Hope this helps,
